Knockdown Portable Ovens, oi which the following is a specification.

My invention relates to portableovens of the character employed inconnection with gas, asolene or other vapor stoves, and it is the o jectof my invention to provide a new and useful oven of this nature capableof being knocked down for convenience and economy in shipping and forother purposes, and the invention will be readily understood from thefollowing description and claims, and from the drawings, in whichlatter:

Figure 1 represents a perspectiveview of my improved portable oven inset-up relation. 2 is a vertical longitudinal section of the same on aline corresponding to the line z-2 of Fig. 3. Fig. 3 is a horizontalsection of the same, shown on a line corresponding to the line y-y ofFig. 2, with the bottom deflectorlate removed. F' 4 shows the outside wals of the oven in ock-down relation. 5 shows the parts composing theoutside casing of the oven in perspective and in separated relation. Fi6 is a pers ective view, showing the outsi casing of t e oven in partlyassembled relation, with the top and bottom omitted. Fi 7 is a rspectiveview of the same in part y assem led relation, with the top in sition,the bottom being omitted and the ining being in part1 assembledrelation. Fi 8 is an enlarge detail in horizontal section showing thecorner construction of the outer body of the oven in separated relation;and, ig. 9 is a similar view of the same in assembled relation.

In its preferred .form the oven comprises a side wall having the endsreleasably bin (1 thereto, the end walls being adapted to li e laidclosely adjacent to said side wall when the oven is in knock-downrelation, the

other side wall being arranged to be 'releasably secured to the endwalls for forming the outer walls of the body of the oven, the

ing is also arranged in releasable relation.

1 represents'the side wall to which a door 2 is hinged, which may betermed the front.

which they are attached 3 4 represent the end walls.

5 is te other side wall, which may be termed the back. 4

6 is the top and 7 is'the bottom.

8 is the back lining, and 9.10 are the end linings which cooperatetherewith to form upright inside linings, and 11 is the inside toplining.

12 is the deflector-plate.

13 are shelves. The shelves and deflectorplate are supported on supports14 formed in the end linings.

'Each of the end walls and the sidewalls are at each of their lateraledges provided with a reversely-bent flange 18 slightly spaced from thebody of the wall from which it is bent by the space 19.

21 are cornerpieces, shown as anglestrips. These an the relatively anged we s 22, the outer lateral edges of which are respectively inwardlyand reversely-bent for forming the and in thus setting up the oven thean cs 23 of the corner-pieces are received by t e spaces 19 at thelateral edges of the ree-stripsare formed with spective body walls ofthe oven. The flanges 18 at the respective lateraledges of the bodywalls are received by the spaces 24 of the corner-pieces. In thismanner" the corners are formed without exposed uncut edges.

In practice, the corner-pieces at" two of the corners (see Figs. 4 and5). are

placed in position at the factory so that in packin for shi' ment theends wall's ma be aid su stantial close to the side-wal s whileremaining re easably attached thereto for convenience and furtherthereby taking up little 5 ace. The construction of the parts toget erwith the resiliency of the metal are such as to permit this to be done.

When setting u the oven, these end walls,

outwardliy so as to be substantially at right ang es to the sidewall toand the other or the side walls laced adjacent to the free edges of theen walls preparatory to formbeing thus attac ed to one of the sidewalls, 7 are swung top and bottom being detachable. The linerablyoutside the upper ends of the cornor-pieces. These flanges and the bodyadjacent said upper edges are provided respectively with registeringapertures 27 28, bolts 29 passing through said registering apertures andhaving nuts 30 for clamping the same in position. The oven-body as faras set up is then reversed into upsidedown position as shown in Fig. 7and the top lining inserted in place. This top lining is provided withupwardly extending edge flanges 33 (see Fig. 2) which have recesses 34therein for accommodating the bolts 29. The back lining and end liningsare thereupon inserted. (See Fig. 7.) The bottom is then put inposition. This bottom is formed up with depending flanges 37 terminatingin upwardly extending reversely-bent flanges 38 forming channels 39adapted to receive the lower ends of the bodyof the oven. Bolts 40 arereceived through apertures 41 adjacent the lower edge of said body andapertures 42 in the flanges 38, the bolts being clamped in position bynuts 43. The lower ends of the corner-pieces are also received withinthe reversely-bent flanges 38. This forms a very secure releasablereinforced bottom edge for the assembled oven upon which it issupported. This bottom is provided with an opening 45 through which theflame is received against the deflector-plate 12.

The deflector-plate and shelves may be inserted through the door openingafter the oven has been set up.

My invention presents an oven which is capable of being collapsed andshipped and stored in knock-down form, taking up little space, andprovides an oven which is conveniently set up and when set up has theappearance of an oven made with permanent sea-ms. It is further strongand compact and of rigid structure. I

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:

1. In a knock-down ortable oven, the

combination of collapsib e walls, and a top and bottom, the said bottombeing provided with depending flanges received inside said walls andupwardly extending flanges received outside said walls, said topprovided with downwardly cxtendin flanges received outside said walls,bolts tor securing said top in place, upright inside linings receivedwithin and supported by said walls, and an inside top lining supportedby said upri ht inside linings and provided with upwardly extendingflanges, substantially as described.

2. In a knock-down ortable oven, the combination of collapsib e walls,and a top and bottom, the said bottom being provided with dependingflanges received inside said walls and upwardly extending flangesreceived outside said walls, said top provided with downwardly extendingflanges received out-side said walls, bolts for securing said top inplace, upright inside linin'gs received within and supported by saidwalls, and an inside top lining supported by said upri ht inside liningsand provided with upwardly extending flanges having recesses therein foraccommodating said bolts, substantially as described.

3. In a knock-down ortabie oven, the combination of collapsib e walls,and a top and bottom, the said walls comprising end walls and sidewalls, each of the lateral edges of said walls being provided with areversely bent flange slightly spaced from the body of the wall fromwhich it is bent, releasable corner-pieces which are of right angularform in cross-section, each of the lateral edges of said corner-piecesbeing provided with a reversely bent flange slightly spaced from thebody of the cornerpiece from which it is bent, said cornerpieces beinslidable lengthwise of the said walls and t e flanges thereof receivedunder the flanges at the lateral edges of said walls of said oven forforming the corners of said oven, the said bottom being provided withdepending flanges received inside said walls and upwardly extendingflanges received outside said walls, said top provided with downwardlyextending flanges received outside said walls, releasable bolts forreleasably securing said top to said walls, upright inside linin sreceived within and supported by said wafis, and an inside top liningsupported by said upright inside linings and provided with u wardlyextending flanges having recesses t erein for accommodating said bolts,substantially as described.
